Founder brief

Who should attend

Technical founders, engineers, and product builders seeking a competitive weekend sprint will find this valuable. Anyone aiming to test out product prototypes rapidly or assemble a project team around technical challenges should consider signing up.

What happens

Participants gather in San Francisco starting at 10:00 on October 31 and work through November 1 under the theme of a technical Halloween sprint. Builders collaborate over two days toward competing for a share of 10k in prizes.

Who's in the room

Developers, creators, and technical community members convened by STRANGER BUILDS and NERDCONF assemble for the sprint. Attendees focus on hands-on development rather than investor presentations, as formal pitching opportunities are absent from the schedule.

How to prepare

Formulate potential project concepts in advance and configure your development environment before arriving Saturday morning. Bring your hardware setup, chargers, and any code libraries you plan to rely on so your team can dive straight into implementation.
